Problem

Biomedical Systems, Inc. had been working with one of our engineering partners on the design of a portable heart monitoring system. The electronics package was complete but the company needed an attractive, ergonomic housing for their body-worn sensing module and its accompanying hand-held controller. The sensor would be worn continually, so comfort and small size were driving factors. The keypad layout of the controller was to be very simple, yet the controller had to be intuitive to use.

Solution

To keep the sensor as small as possible, we designed a housing that was essentially shrink-wrapped around the electronics. Even with the tight dimensions required, we were able to give the top of the housing a striking rounded treatment that we carried through to the controller module. The rounded top softened the form substantially.

The electronic architecture was such that all components were attached to a chassis that was sandwiched between the top and bottom housing. We reflected this by accentuating a band at the middle of the form. By designing the band this way, we made both the controller and the sensor appear smaller.

The controller’s keypad was designed with four cursor controls and an enter key in the middle, all unified with a circular mirror-finished textural surface that is achieved at no cost (other than the cost of polishing the mold in that area) in the molding of the top case half. The controls are completed by two soft keys at the location on the display where operative text appears.

Result

TruVueBiomedical Systems’ TruVue wireless ECG monitor has been helping heart patients live healthier lives since the product’s debut in 2012.
